I was gifted a Rolex watch by a brand through my job late last year and I’ve been trying to figure out how to authenticate it ever since. The product did come with a warranty card, but it’s not filled out. I did take it to a Rolex store and was told they could not authenticate the watch in store and that I would have to send it out through their authenticator for upwards of 1k. Does anyone know how I can confirm the authenticity of the watch through any third party sources without spending an arm and leg?
